To all whom it may concern: I

Be it known that I, Nous H. NELSON, a citizen oi the United States, and a resident of Willmar, county of Kandiyohi, and State of Minnesota, have invented a new and useful Power Dun1ping-Vehicle, of which the following is; a full, cle: r, concise, and exact specification,

, My invention relates to vehicles designed for the transportation of heavy commodities or live stock, and to means for unloading or dumping same. I 4

Nhen hauling heavy commodities by wagon, a considerable time as well as labor Said tually decreased by noviding means for elevating the forward portion and lowering the rear portion of the receptacle in which the commodity is placed, thereby discharging the load rearwardly therefroi'n by means of gravity. Live-stock are often subject to injury when unloaded from wagons, however, by lowering the rear portion of the wagon box, this difficulty is eti'ectually reduced to aminimum.

In producing devices for the purpose of discharging loads from wagons in the aforcstated manner, it has been the universal pram t 1ce to provide some form oi platform upon which the wagon is driven, the horses unhitched, and the entire platform and wagon tilted to a suitable angle for discharging the load by gravity. Devices of this nature are more or less bulky and clumsy, are not easily transported, and, require an expenditure of a considerable energy for their operation,

owing to the excessive weight elevated.-

They' also require a separate motive agent, such as a horse or a mechanical motor, there by involving an excessive expense for maintenance as' well as the purchase cost.

Theobject of this invention is to obviate the foregoing disadvantageous conditions, by providing a vehicle with self-contained means for tilting the receptacle in which the load is carried, said means being actuated by the propelling agent of the vehicle. In case ,1he vehicle is tiwnisported by horses, means are provided whereby the receptacle is tilted by said horses without disengaging the traces from the double-trees.

The invention is readily applicable to all common horse-lra\\'n wagons,

advantage in connection withany of the various forms of motor-trucks adapted for the transportation of heavy comn'lodities of such nature as would permit unloading by gravity process.

In attaining the object of my invention I provide a simple construction comprising few and durable parts, which may be manufactured and assembled at a comparatively small cosh, which is conveniently operated, and which will perform its requisite functions at a high standard of mechanical etticiency.

To enable those skilled inthe art, to which my invention appertains, to more fully understand the principles of construction and them-any advantages attending the use of same, a self-dumping vehicle embodying my invention is forth in the following specification and illustrated in the accompanying drawings; however, the actual scope of my .invention is more part cularly pointed out in the subjoined claims.

In the drawin s Figure 1 is a longitudinal elevation of selt-dumpii'ig vehicle embodying my inwzntion, the receptacle being shown tilted as in position fordischargingits load. a -4 is a longitudinal section thereof, the receptacle eing shown in horizontal position. 3 is a detail of the hoisting mechanism, bein a front View thereof. Fig. is a detai of the anchorstay. Fig 5 is a sectional detail taken on the line 5 5 of Fig. 1. And Fig. 6 is a detail showing a modified construction of the anchor-stay tip.

Referring to the drawings-in detail, similar reference characters indicate like parts throughout ,thespecification, and the several views of the drawings.

The wagon proper consists of the usual running gear A, and the receptacle B, which are wcl known and need no detailed description herein. The receptacle B is shown in form of a grain tank, however, the term Big.

receptacle as herein used applies to any' being disposed upon either side of 'tions 8, and consists of the longitudinal stringers 9 and 10, at substantially the forward portions of which is secured a transverse beam 11. The supplementary :t'rame is of similar to the main frame, and depends therein when in a horizontal posit-- tion. The design aims to maintain a constant transverse relation between the main frame and the supplementary frame. but atlowing perfect freedom of pivotal movements in the vertical plane.

X. provide at. the front portion of the main frame a hoisting mta-hanism E for the purpose of elevating; the forward portion of the supplementary frame and r aceptaclc, the

.hoisting lirarneoi which is pivotally secured upon the main frame by means oi suitable connections as 12. Said hoisting frame com-- prises the upright timbers l3 and ti the upper portions of which a re laterally lnacmil by the crown-twain l5.

I provide a transv so shalt 1c, rotativcly mounted in suitable journals which are sccured upon the trout. faces of the lnu'ight timbers l3 and 1.4. and 2 -rubst.=iutially their lower portions. The actuating;- drum '1? is secured upon. said shaft in, being li'lt'ei'llitftllately disposed thereon; and the hoist-drums and 13' are mounted upon said -shatt lo id. drum 1'? at st "tantiatly the ezctien'ie portion. ot? d Silt. to which they are rigidly sccin'ed for rotation with said actuating drum.

Tin: cable is seeurtd upon the drum t? from which it extends dcamnvartlly passing; over the idle sheave acncc it ext. it forwardly and is anchored at the cen ral portion oi the doubletree This cable normally remains reeled upon the drum 1?; and. when unreeledi ritatively impels the drums and shaft as indicated by the arrow. The cables and 24 are secured upon the hoist drums 18 and 19 respectively, and c ztend. upwardly, gassing over the sluiayes 2-3 and 26, from which they extend downwardly and are anchored to the extreme tormugtl. portion of the supplementary trame t), 'lhesc cables renniin norms tty extended trout their respectivereels and are wound upon rid drums, when the cable 20 is cxteudert drawing up the forward pt'u'ttion ot' the sugr plemeutary frame to a po lion as indicated inl ig. 1 oil' the drawin,

A pawl 28 is suspended from the beau'i 27 and. is adapted to engage a ratchet which is preferably formed upon the pe riphery oi the flange ot the actuating drum 1?, thereby preventing backward monuments oi. the drum 17 until desired. he annular friction rim C30 is mounted upon the shat! l6, and if desired, may be formed integral with the drum 1?; and is encompassed by a brake strap 31 which controllird by the actuating lever 32 pivotatly depending upon said transverse heme 'PIOYLtl means as bolts 1:

Upon the rear face of the uprights 13 and 1.4- J. provide rails 33 and 34, extending the entire length thereof, and traversed by the anti-friction rollers 35 and 36 which are held in contact therewith by the tension of the cable extending from the uprights t0 the supplementary frame D. Said antit'riction rollers are mounted in suitable castigs 3? and 38, said castings being also pr0- aided with eyelets by which the cables 23 and 2t may be conveniently secured thereto.

11? desired the supplementary frame may be discarded, and the hingeplates for the pivot connections 8 and the castings. 37 and 38 secured direct upon the receptacle. This would necessitate equipment of various retizeptacles with these connections; 'or contine the use of the vehicle to one receptacl li owever, the. provision of a supplementary frame provides greater convenience for changing receptacles.

An anchor stay I is pivotally secured upon the main frame O; and comprises the longitudinal stays Ell -and it), the forward portions of which are transversely secured by a suitable beam ll. At the .torward portions of the stays I provide suitable tips 42, which are secured to the plates by any ap- Said tips are px 'ovided \vith tlukcs ll which extend downwardly and somewhat; 't'orwardly therefrom and are :nlaptcd to very positively engage the soil. These tips are illustrated as formed oil? common angle steel, the' lower Jlangc ot' the angle 'torming the fluke; how-' ever, this construction may be modified as shown in Fig. (3 Ojl the drawings, in which the tips are in form of caps inclosing the end portions of the stays, the tlukes being formed ral therewith. 'lhisntodified construc- At the rear portions of the stays I provide suitable angular plates "which are pixotally secured to the stringers 2 and 3 of the main frame by means of bolts 46. ".ihc cable t?" is central y secured upon the beam ll, [muses over the idle sheaves 4S and li and provided with a suitable eyelet by which it. may be detachably secured upon the pin 50, which is atlixcd to the drum 17. It. desircth the angular plate 45, may be sub: 'uted by straight plates, secured upon the side faces ol" the stays 3t) and 4-0; or it desired suitable castings may be formed cou'ipletcly int-losing the upper endportionsof the stays thereby providing ample protection against a too rapid deterioration of same. v

When I desire to discharge a load from tho recc itacle, I first release the cable 47 from engagement with the pin 50, allowing the anchorstay F to drop assuming a position as indicated in Fig. 1 of the drawmessy:

mgs. I then release the double-tree iron! connection with the draft-tongue, and d 'ive 2; 'This rotation causes the drums l8 and 19.t0 wind up the cables 23 and 2 thereby raising the forward portion of the supple- -mentaryframe D, the portion of the receptacle extending to the rear of the pivotal connections 8 being correspondingly lowered. 'The anchor-stay 'F, engaging the ground, tends to withhold the vehicle from moving forward in response to the forward exertion of the cable 20. The ratchet 29 is engaged by the pawl 28 thereby retaining the supplementary frame and its receptacle in a tilted position until the load is discharged; after which, the pawl is released, and the brake operated to prevent the supplementary frame from descending too rapidly. To raise the anchor-stay from its operative position, I secure the eyelet of the cable 47 upon the pin 50, the downward momentum of the supplementary frame causes the drum 17 to rotate in opposite direction from that indicated by the arrow, thereby winding the cable 4-? upon the shaft 16 and raising-the anchor-stay l" to a po sition as indicated in Fig. of the drawings.

In applying this invention to motortrucks, devices similar to this herein set forth maybe provided for aising and lowering the supplementary frame also for ac tuat'mg the anchor-stay. The cable hoist. may be substituted by a traveling-screw or any other approved means. It should be noted however, that this invention prm'idesv means whereby the receptacle and its load only are tilted, thereby obviating the ex cessive expenditure of energy necessary. for raising the entire running gear. The in vention is self-contained in the vehicle, whereby it may be utilized at. any desired point. without transporting a dump-jack or other bulky mechanism from place to place. It should be also noted that the mechanism is adapted for operation without unhitchin the horses from the double-t ree.

%t is not to be understood by the term supplementary frame that the invention is confined to the use of a supplementary frame and a recepta do detachably secured thereon. The term, as used in the claims, includes any cquipollcnt cim triu-tiouz '1'. (1.,

the connection of the receptacle direct. upon the main frame. Likewise the term anrhor-stay. as herein used, denotes any eonfiguration of device for retarding forward movements of the vehicle during the elevation ofthe supplementary frame. The construction herein set forth has the advantage of impinging upon the soil direct, whereas, a brake engaging the wheels would not prevent the wheels from sliding over the ground.

It. is obvious from the foregoing that vari ations may be effected, as defined by the scope of the appended claims, without departing from the true and. original purportof ray invention, tl'iereifore I do not confine myself to the details ofeonstruction and operation hereinbefore set forth.

Having thus described my invention what I claim and desire to secure by Letters Patent of the United States is the following:

1. In a powendumping vehicle, the combination with the running gear, of a main frame, a receptacle mounted thereon, mechanism adapted to elevate a portion of said receptacle, an anchor stay adapted for engagement with the ground, and means connecting said anchor stay with said elevating mechanism. whereby the downward gra vitation of the receptacle applied for elevatsaid anchor stay, substantially for the purposes set forth.

in a power-dumping vehicle, the combination with the running gear; of a main frame; a receptacle pivotally secured thereon; a hoisting mechanism adapted to elevate a portion of said receptacle; an anchor stay adapted for engagement with the ground; and means connecting said anchor stay with said hoisting mechanism whereby the downward gravitatimi of the receptacle, when lowered to a horizontal position, is utilized to effect the disengagement of said anchor stay from the grouiul, substantially for the purposes set fin'th.

3. In a selfdnmping vehicle, the combination with the running gear, of a main frame, a. s1ipplemei'itary frame pivotally secured thereon, a hoist-frame mounted upon the fmrward portion of id main frame, hoist drums mounted in said hoist-frame, an actuating drum niounted to rotate with said hoist-drun'ls, a cable connecting said actuating drum with the double-tree, means opcratively comiecting said hoist drums to the forward portion of said supplementary frame, an anchor-stay pivotally mounted in said main frame and provided with iiukes adapted to engage the soil, a cable secured upon said anchor-stay and detachably sccuicd to said actuating drum avhcreby the downward momentum of thesupplementary -frame when lowered is applied for raising the anchor-stay, substantially for the purposes set forth.
